That WSJ has to be subscribed to I think, as it did not work to “continue” reading it.
I think this Times of Israel article is based on it though.

Rescued hostages were held by families with known ties to Hamas, says report
Nuseirat residents tell Wall Street Journal they were surprised to learn about the presence of four Israelis in the camp, and some are 'furious' that Hamas endangered them….
Obviously, firstly, there should not have been hostages, and secondly this put other residents in grave danger. As the alternative place to keep them would have been tunnels, however, being in a family flat in the way Noa was would seem to be preferable imo ( not that any of it is all right).
Given the circumstances I can see the IDF would have felt justified, and found it easier just to kill the whole families, then blown up their houses, but might it have been at all feasible perhaps to have tied up or wounded anyone unarmed, then imprisoned them pending a trial? This might have led to more useful information too.
We do not know what connection to terrorist-Hamas, as opposed to administrative offices, the families had
or if they were coerced into taking on the keeping of hostages.
As for this, from Hagari below, this question has been done to death on this thread, but it is not true.
“We know about under 100 [Palestinian] casualties. I don’t know how many of them are terrorists,” IDF Spokesman Daniel Hagari said.
The BBC report said:
Gaza's Hamas-run health ministry said 274 Palestinians were killed and 698 others were injured during the operation. Its figures do not differentiate between civilians and combatants.
The Hamas-run Government Media Office reported that 64 children, 57 women and 37 elderly people were among the dead.
(158 children, women and elderly killed many others injured.)
